SPRING FOOT-BOARD.

SPECIFICATION formingpart of Letters Patent No. 271,256, dated January30, 1883.

Application filed June 23, 1882. (No model.)

To all whom it may concern:

Be it known that we, EMERY N. MOORE and THOMAS N.ANDERSON, ofBoston, inthecounty of Suffolk, State of Massachusetts, have invented a certainnew and useful Improvement in Spring Foot-Boards, of which the followingis a description sufficiently full, clear, and exact to enable anyperson skilled in the art or science to which said invention appertainsto make and use the same, reference being bad to the accompanyingdrawings, forming a part of this specification, in which- Figure 1 is anisometrical perspective view, and Fig. 2 a vertical longitudinalsection.

Like letters of reference indicate corresponding parts in the differentfigures of the drawlugs.

Uuriuvention relates toanew article of manufacture designed principallyfor the use of horse-car drivers, locomQtiveengineers, 850., the natureof which will be readily understood by the lollowing brief explanation,its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the body or casing,and B the platform,which are preferably rectangular in shape, and maybe constructed ofeither metal or wood, as desired.

The body is provided with an outwardlyprojecting lip or horizontalflange, a a, at its upper side, and on its lower side with the i11-army-projecting flange d d, the flange a being designed to rest upon theframe-work or floor c of the car, locomotive, or other vehicle on whichit is used, and support the board.

Projecting vertically from the under side of the platform B are fourstuds, in m, provided with coiled springs Q7 v, the lower ends of thesprings resting on the top of the flange d, and the upper ends abuttingagainst the under side of the platform or against the flanges m w on thestuds m m. The springs act expansively, and are designed to keep theplatform B elevated slightly above the plane of the body A when there isno pressure on the same.

Itis wellknown that thedriversof horse-cars, locomotive-engineers,&c.,receive serious bodilyinj ury and become greatlyimpairedin healthfrom being constantly subjected to the jarring or vibratory movementsofthose vehicles-editficulty which our invention isdesigned to obviate.In its use the body A is preferably let into the floor or platform ofthe car, locomotive, or othervehicle until the flange (0 is flush withthe same.the person usingit standing on the platform B, the springs e oneutralizing or taking up thejarring or vibratory movements in a mannerwhich will be readily obvious to all conversant with such matteiswithout a more explicit description.

It will be obvious that our improvement is not confined in its use tohorse-cars or locomotive'engines, but may be employed as a standingplatform or spring foot-board wherever it is necessary to obviate thedisagreeable or iiijurious effects arising from vibratory or jarringmovements similar to those experienced by the drivers of horse-cars andlocomotiveengineers in the performanceof their duties.

Having thus explained our improvement, what we claim is-- As a newarticle of manufacture, the improved spring foot-board described, thesame consisting of the body A,springso o,and platform B, provided withthe studs m in, constructed and arranged to operate substantially as setforth.
